I have really bad stress and PTSD, which caused OCD so I constantly wash my hands and I won't touch any kinda food without a fork. Is anyone like me and how do u control it?

I've got this problem. I could wash my hands up to five times in five minutes and certainly more than once in every couple of hours.
I made a 10 point dirt scale recently and am trying to minimise the washing with soap part. Maybe that could help.
